Johannes Beckers is a co-author on two Atlas studies that relied on large-scale mouse phenotyping, the systematic measuring of many body functions in the same animals. EIS2016 showed that oral spermidine, a natural compound also found in food, lengthened the lives of mice, kept heart muscle from thickening and kept the heart able to relax normally between beats. The benefit disappeared in mice whose heart muscle cells lack the autophagy gene Atg5, so autophagy, the cell's self-cleaning system, was needed for the effect. The paper also included a human diet survey linking spermidine intake to lower blood pressure and fewer heart problems, but that part is observational and cannot show cause. NEF2013 gave rapamycin, the drug that blocks mTOR, to young and old mice and measured a very wide panel of body functions. Rapamycin lengthened life but changed only a few of the classic signs of ageing, so a longer life did not mean that ageing slowed down across the whole body. Both are mouse studies.
Beckers works at the Institute of Experimental Genetics of Helmholtz Munich in Neuherberg, near Munich, and PubMed records also list the Chair of Experimental Genetics at the Technical University of Munich and the German Center for Diabetes Research. The German Mouse Clinic at Helmholtz Munich tests mouse models in a standardised way across many organ systems; its recent papers cover heart size, movement, behaviour, metabolism and blood values. In both Atlas papers Beckers appears among the German Mouse Clinic authors. Beckers's own papers centre on measuring which genes are switched on in tissues, for example with Marion Horsch and Martin Irmler, and range from mouse genetics to the effects of air pollution on the lung, as in a 2026 study of wood-smoke aerosols.
